No, my mistake again; Mark's got the rocket launcher, right? It's a quad-barrel design, so he's still got three more to go.
Right now, the squad is arranged in this order from left to right; Kelly, Terrance, Mark, Ylfa, Richard, Rachael, and Max. The arrangement of the six hostiles everyone is attacking is similar as well, with everyone going for the ones in front of them. If you want to change targets, make sure to say which number it is from the left or right. Keep in mind however, that Kelly is the odd one out; she's covering for Terrance and Mark with the flamethrower.
Also, Terrance is the only one without PA?
